described in a paper written by F. W. Putnam in 1863,- has been the
subject of considerable debate. As each of the new names is followed
by "Agassiz, MS. (Nov. sp.)," most succeeding references have cited
Agassiz as their describer. Some still contend that Putnam is the
authority, as he wrote the paper and at no place in the text is it
stated clearly that Agassiz was responsible for anything other than
coining the new specific names. In view of the disagreement the
authorship of these species is best cited as "Agassiz, in Putnam."

Figure 5. Pigmentation patterns of: A. Adult N. zonatus, UMMZ 152697, 68
mm SL, from Barren Fork, Tuscumbia, Miller County, Missouri. B. Adult N.
pilsbryi, UMMZ 80987, 65.5 mm SL, from Elk River, Grove, Delaware County,
Oklahoma.

 Past references to N. zonatus often apply entirely, or in part, to
another species, N. pilsbryi. These forms were regarded as identical
(Hubbs and Brown, 1929:36; Hubbs and Ortenburger, 1929:81-82)
until 1940, when Hubbs and Moore pointed out several well-defined
morphological differences in addition to differences in range. They
regarded the two forms as only subspecifically distinct, but presented
evidence indicating that this was possibly a conservative separation.
 DIAGNOSIS. A small species of Luxilus, rarely exceeding 85 mm
SL. Distinguished from other species of Luxilus (except N. pilsbryi)
by: A prominent black lateral stripe that encircles snout and is present
at all ages; a well-developed, narrow, secondary lateral stripe situ-
